Add Watermarks To PDFs With API

CraftMyPDF supports RESTful API integration. The integration with REST API makes it easy to auto add watermarks to PDFs in your application.

Drafts, confidential reports, quotes and licensed documents all need marking — and on every copy, not just the ones someone remembers. Stamp text or image watermarks as the PDF is generated, at the position, rotation and opacity you set.

Design the template once in our drag-and-drop editor, then POST your JSON — your watermarked PDFs come back with tables, images, barcodes and QR codes rendered from your data. Any language that speaks HTTP works, with no PDF library to maintain.

Tutorials and Latest Articles

Frequently Asked Questions

How does the API add a watermark?

There are two ways. If CraftMyPDF is making the PDF for you, add the watermark to the template once, as text or an image and set where it sits & how it is angled. Every PDF made from that template will have it. If you already have a PDF, send it to the API and it comes back with the watermark added.

Can the watermark say something different on each document?

Yes, if the watermark is part of the template. It picks up the same data you send with each request, so a quote can carry the client's name, a report can say “Confidential” and a draft can show the version date, without anyone touching the template in between.

What kinds of documents usually get a watermark?

Drafts, so nobody mistakes them for the final version. Confidential reports. Quotes with an expiry date. Paid material like course notes. Sample tickets too: a ticket template with “SAMPLE” across it can go to a client before the real event tickets are sent out.

We send a lot of confidential reports. Is there more on that?

Yes. The reporting automation page covers the whole process, from pulling the numbers to building the report and sending it. Legal, finance and real estate teams use this most, and the industries pages show the usual documents and workflow for each.

Can I try watermarking without writing code?

You can try the template side without code: build a template with a watermark on it and download the result from your dashboard. If you want to work with files you already have, the free PDF tools include merge, split and rotate, which often come just before or after adding a watermark.

What does it cost, and how much is free?

Adding a watermark to an existing PDF uses half a credit. A PDF made from a template that already has the watermark uses one credit, the same as any other PDF. The free plan gives you 50 credits a month with no credit card, which is enough to set up the template and check the watermark sits where you want it. For everything else the editor and API can do, see features.
